For all the comparisons made between for-profit legacy media and those in the nonprofit sector, I think one of the most favorable is the nonprofit's outreach to its community or communities.
In their quest for a sustainable business model, several nonprofits I've learned about - all online-only startups, by the way - have incorporated social events as part of their ongoing fundraising and marketing campaigns.
Tonight, voiceofsandiego.org is hosting an event called "The People Who Make San Diego Work" - a celebration of interesting people that the site has written about in their People at Work and Virtual Convening series. Admission is free for donors and $20 for first-time donors. It's a small amount, but this is part of the business of developing relationships for the long haul.
